CTkTabview Memory Issue
When using .delete("Tab Name") the CTkFrame that is created during .add("Tab Name") isn't being destroyed, resulting in increased memory usage.
Changing line 333 in ctk_tabview.py to
self._tab_dict[name].destroy()
Seems to help and removes the frame created but there is still memory not being released.
A small example
import customtkinter
class App(customtkinter.CTk):
def __init__(self):
super().__init__()
self.tab_name = 0
self.tabview = customtkinter.CTkTabview(self)
self.tabview.grid()
self.tabview.add("Add Tab")
self.add_button = customtkinter.CTkButton(self.tabview.tab("Add Tab"), text="Add", width=100, command= self.add_tab)
self.add_button.grid()
def add_tab(self):
self.tabview.add(self.tab_name)
self.del_button = customtkinter.CTkButton(self.tabview.tab(self.tab_name), text="Del", width=100, command= self.del_tab)
self.del_button.grid(row=1)
self.tabview.set(self.tab_name)
self.tab_name += 1
def del_tab(self):
self.current_tab = self.tabview.get()
self.tabview.delete(self.current_tab)
print(str(self.tabview.winfo_children()))
if __name__ == "__main__":
app = App()
app.mainloop()
How did you measure? How big is the memory leak? What operating system, versions of Python and CustomTkinter did you use?
Windows 10: Build19045 Python: 3.10.7 CustomTkinter: 5.1.2
Well the leak depends on what is stored in each tab. On the example I posted it's not that noticeable as each tab only has a button. *See Note
The above example was to demonstrate that the frames being created by .add() aren't being destroyed with .delete() which can cause slowdown and increased memory usage.
Line# 333 in ctk_tabview.py needs to be changed to self._tab_dict[name].destroy() as I have put in my PR #1083
*Unless you add a ridiculous number of tabs. Made a loop to add and delete 1000 tabs. Without the change to line#333 the program uses 73.1MB with the change it only uses 29.1MB
